Cost of slowing down?

I was pondering last night... very dangerous, I know.. Well, I was wondering
why the CEV was a larger version of Apollo type re-entry techniques.
I eventually realised that it is in fact lighter and cheaper on all sorts
of fronts.

To get a Shuttle style heat dissipation working for the higher speeds of
coming in from the moon, would be not only more difficult, but heavier, cost
more to launch in the first place because of that, and presumably more
vulnerable, as it will be exposed throughout the flight.

Also, if you wanted to slow down before re-entry, you would need more
fuel...
